Abstract: A truck body for a machine is disclosed. The truck body has a bottom wall defining a front end and a rear end, a pair of lateral walls extending from the bottom wall, and a front wall extending between the pair of lateral walls at the front end. The truck body includes a pair of bottom beams pivotally coupled to a frame of the machine. The truck body further includes a plurality of tubes disposed on the pair of bottom beams. Each of the plurality of tubes is disposed adjacent to each other to at least define the bottom wall and the pair of lateral walls of the truck body.

Abstract: An apparatus for supporting a backing member in an enclosed structure is disclosed. The enclosed structure includes a first plate defining an opening therethrough. The apparatus is configured to be disposed within the enclosed structure. The apparatus includes a clamp member and a support member configured to rotatably support the clamp member. The clamp member is rotatable about a rotation axis defined by the support member. The support member is further configured to abut a second plate spaced apart from the first plate. The clamp member is configured to be moved along the rotation axis relative to the support member and bias the backing member to contact with the first plate along the opening.

Abstract: A system for facilitating welding along an opening defined in a first plate of an enclosed structure is disclosed. The system includes a support device adapted to be inserted between the opening of the first plate. The support device includes a first support member and a second support member adjustably coupled to the first support member. The support device includes a magnet member adapted to detachably couple the second support member to a second plate of the enclosed structure. A pusher member is partially received within a channel of the first support member. A pin member is adapted to selectively engage with one of a plurality of teeth of the pusher member. A backing member is adapted to close the opening from within the enclosure. Further, a cord member is used to move the pusher member and bias the backing member into contact with the first plate.
